#include<stdio.h>
void main()
{
int score,i;
printf("Enter the Student's Score:\n");
scanf("%d",&score);
i= score/10;
switch( i )
{
case 10:
case 9: printf("A\n"); break;
case 8: printf("B\n"); break;
case 7: printf("C\n"); break;
case 6: printf("D\n"); break;
default：printf("E\n");
}
}

另一种：
#include <stdio.h>
void main()
{
char grade;
printf("Enter Grade:\n");
grade=getchar();
switch(grade)
{
case 'A': printf("85~100\n");
case 'B': printf("70~84\n");
case 'C': printf("60~69\n");
case 'D': printf("<60\n");
default : printf("ERROR\n");
}
}

再来一种：
#include"stdio.h"
void main()
{
int score;
printf("enter the student's score:\n");
scanf("%d",&score);
if(score>=90)
printf("A\n");
else
{ if(score>=80)
printf("B\n");
else
{ if(score>=70)
printf("C\n");
else
{ if(score>=60)
printf("D\n");
else
printf("E\n");
}
}
}
}
